Invasive/Damaging Core Sample Testing

 

Non-invasive /  Non-Destructive  Electrical Conductivity Testing

To determine the authenticity of gold bullion – non-destructively and therefore without loss of value – its electrical conductivity is measured using the eddy current method according to ASTM E 1004. This method utilizes the physical fact that fine gold, various alloys and foreign material will all differ in their conductivity, there­fore allowing forgeries to be detect

 

X-ray Fluorescence Analysis (XRFA)

Iis a suitable complement for accurately determining  composition(s).

 

Besides the obvious basic methods of testing.....

Ping/Resonant Testing

Magnetic Gause Field Testing

Thermal Conductivity Testing
